English is not my native language, but I don’t think “corporeal” and “incorporeal” are the right words to describe the duality between particle and wave … which is actually valid for ANY particle, it’s just easiest to study it on light.

Also, you don’t need microscope to observe something in the quantum mechanics sense. Whatever is doing the disintegrating thing must be more complicated. I suppose there were lot’s of studies just about this phenomen … doesn’t mean they found anything, but negative results are results too :-)

I am still holding onto the idea that the “sperm” was all that remained of the being supposedly killed by the Nazies. (Normally for regenerative entities the largest part left behind is what regenerates and unless it is a duplicator the remaining mass dies or dissolves). So if this being were reduced to nothing but a small sample, then maybe that small sample would remain, and due to some passed down esoteric cult type deal (this would be a story detail which I can’t really guess on) but somehow it ended up as a sperm donor sample, and bing to the boom that was used and grew/regenerated in a fertile ground to produce Sparrow, and after such a traumatice regeneration total amnesia and temporary loss of abilities.
